A plant species exhibits cleistogamous flowers alongside chasmogamous flowers. What is the PRIMARY advantage conferred by the cleistogamous flowers?
Increased genetic diversity through cross-pollination
Assured seed set even in the absence of pollinators
Attraction of a wider range of pollinators
Production of larger and more nutritious seeds
Which of the following statements about chemotaxonomy is incorrect?
It uses chemical constituents of organisms for taxonomic classification.
It can be useful in distinguishing closely related species with similar morphologies.
It can help in understanding evolutionary relationships.
It relies solely on morphological characteristics for classification.
The polyphyletic grouping of organisms is based on:
Shared ancestral characteristics.
Homologous characteristics derived from a common ancestor.
Analogous characteristics due to convergent evolution.
A combination of ancestral and derived characteristics.
In numerical taxonomy, the principle of 'overall similarity' emphasizes:
Prioritizing specific key characters over others.
Focusing on derived characteristics rather than ancestral ones.
Considering a large number of characters and giving equal weight to each.
Using only morphological characteristics for analysis.
Which of the following is not a limitation of classical taxonomy?
It relies heavily on morphological characteristics, which can be subject to convergent evolution.
It may not accurately reflect evolutionary relationships.
It can be difficult to distinguish between homologous and analogous traits.
It incorporates molecular data for a more comprehensive analysis.
